    Has anyone found a solution yet?  We are facing the same problem when copying files from one USB storage device to another USB storage device.

    Hi,

    It is possible that this is related to the linux kernel.

    As far as I know this use case was not validated on this device.

    I would encourage you to check the linux community if there is a fix for such an issue.

    thanks
